Key Applications of Urethane in Metal Forming Processes

In the field of metal forming, high-performance elastomers are crucial in press systems. Metal forming companies often seek the expertise of vacuum casting specialists for custom parts or replacements for conventional rubber components. These specialists possess the necessary technology, skills, and expertise to cast urethane parts efficiently, quickly, and with precision. By incorporating cast urethane parts, metal-forming businesses can reduce costs, minimize machine maintenance frequency, and improve production quality.                          

Here are several primary applications of urethane in metal forming: 

Urethane pads

Urethane sheets or pads, essential components in metal forming, act as overlays in presses. These pads are crucial cast urethane parts, offering a layer of protection when forcing metal sheets into custom-molded dies. They also extend the lifespan of various types of presses, including mechanical, servo, and hydraulic. When selecting urethane for these pads, it’s important to consider materials within the 50D or 70A to 90A durometer range. This range offers optimal shock absorption, hardness, and tear resistance while still being soft enough to distribute force evenly across the metal’s surface without causing damage.

Urethane overlays

Fluid cell presses (commonly used in cold metal forming) are particularly effective for producing intricately designed metal components with precision. This method is often employed in creating custom aerospace parts. Cast urethane parts play a pivotal role in ensuring the success of the fluid cell process.

Urethane overlays on pads facilitate even pressure application on the metal sheet, allowing it to take the exact shape of the stationary tool and enabling faster formation of the part. These materials can withstand extremely high pressures during inflation, and their high rebound ensures the pad returns to its original shape, maintaining consistency in the process.

Custom urethane parts

Custom urethane parts are suitable for metal forming involving both thin and thick sheet metal blanks. When seeking such specialized components, it’s beneficial to collaborate with experienced manufacturers of cast urethane parts, like HLH Prototypes. They can provide parts tailored to your needs, ensuring essential qualities like rebound and tear strength are met.
